How to solve java.lang.NoSuchFieldError: LUCENE_7_7_2

[apar]

Hi, I'm using the elasticsearch 7.6.2 and I'm trying to create an index and update the mappings in a second step. The index gets successfully created, however the mapping update fails with the following error:

nested exception is java.lang.NoSuchFieldError: LUCENE_7_7_2] with root cause
java.lang.NoSuchFieldError: LUCENE_7_7_2
	at org.elasticsearch.Version.<clinit>(Version.java:111)
	at org.elasticsearch.common.io.stream.StreamInput.<init>(StreamInput.java:113)
	at org.elasticsearch.common.bytes.AbstractBytesReference$MarkSupportingStreamInputWrapper.<init>(AbstractBytesReference.java:195)
	at org.elasticsearch.common.bytes.AbstractBytesReference$MarkSupportingStreamInputWrapper.<init>(AbstractBytesReference.java:189)

My code looks like that:

 private void createIndex(String indexname) {
  String indexname = "myIndex";
    try {
	  RestClientBuilder builder = RestClient.builder(new HttpHost(hostname, port, scheme));
      RestHighLevelClient client = new RestHighLevelClient(builder);
	  
      CreateIndexRequest indexRequest = new CreateIndexRequest(indexname);
      CreateIndexResponse createIndexResponse = client.indices()
          .create(indexRequest, RequestOptions.DEFAULT);
		  
      if (createIndexResponse.isAcknowledged()) {
		// Index gets created, proceed to update the mappings
        updateIndexMapping(client, indexname);
      }
    } catch (Exception e) {
      log.error("Unable to create the elasticsearch index : [" + e.getMessage() + "]");
    }
  }
  
  
  private void updateIndexMapping(RestHighLevelClient client, String indexname) {
    try {
      PutMappingRequest request = new PutMappingRequest(indexname);
      XContentBuilder builder = XContentFactory.jsonBuilder();
      builder.startObject();
      {
        builder.startObject("properties");
        {
          builder.startObject("date");
          {
            builder.field("type", "date");
          }
          {
            builder.field("format", "dd.MM.yyyy");
          }
          builder.endObject();
          builder.startObject("location");
          {
            builder.field("type", "geo_point");
          }
          builder.endObject();
        }
        builder.endObject();
      }
      builder.endObject();
      request.source(builder);

      if (!client.indices().putMapping(request, RequestOptions.DEFAULT).isAcknowledged()) {
		log.error(String.format("Unable to update the mappings for index %s.", indexname));		
      } else {
        log.info(String.format("Mappings for index %s successfully updated ", indexname));
        // Mappings updated, procced with saving a doc ..
      }
    } catch (Exception e) {
      log.error("Unable to update the index mappings : [" + e.getMessage() + "]");
    }
  }

My pom includes the elasticsearch version as a property
<elasticsearch.version>7.6.2</elasticsearch.version>

and I have both elasticsearch and elasticsearch.client as dependencies :

<dependency>
  <groupId>org.elasticsearch</groupId>
  <artifactId>elasticsearch</artifactId>
  <version>${elasticsearch.version}</version>
</dependency>
<dependency>
  <groupId>org.elasticsearch.client</groupId>
  <artifactId>elasticsearch-rest-high-level-client</artifactId>
  <version>${elasticsearch.version}</version>
</dependency>

Lucene is also present for other project purposes:
<lucene.version>8.1.1</lucene.version>

    <dependency>
      <groupId>org.apache.lucene</groupId>
      <artifactId>lucene-core</artifactId>
      <version>${lucene.version}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.lucene</groupId>
      <artifactId>lucene-analyzers-common</artifactId>
      <version>${lucene.version}</version>
    </dependency>

mvn dependency:tree -Dverbose -Dincludes=org.apache.lucene Gives the following :

Our spring-boot-version is 2.3.0 if that helps. Any ideas on how to solve this problem? Thanks in advance

[dadoonet (David Pilato)]

When using springboot with elasticsearch, you need to be explicit with some transitive dependencies as SpringBoot declares a version 6.4...

Basically you can put this in your pom.xml:

<properties>
  <elasticsearch.version>7.7.0<elasticsearch.version>
</properties>

See documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto-customize-dependency-versions

Thanks for responding.
My problem was solved after upgrading to Lucene 8.5.2 .
I'm declaring the rest-high-level-client dependecy which uses the spring-boot elastic dependency. (Spring-boot 2.3.0 declares the elasticsearch 7.6.2 dependency )

<dependency>
  <groupId>org.elasticsearch.client</groupId>
  <artifactId>elasticsearch-rest-high-level-client</artifactId>
</dependency>
